Cardiff Council elections

Cardiff Council elections take place for the whole council every five years, to Cardiff Council (officially the County Council of the City and County of Cardiff) in south Wales. It came into being as a unitary authority on 1 April 1996, after the passing of the Local Government (Wales) Act 1994. In 2014 the National Assembly for Wales deferred all local elections in Wales to 2017. The council is composed of 75 councillors.

Between 1974 and 1996 Cardiff Council was a district council of South Glamorgan (the city also electing councillors to the county council). Prior to 1974 Cardiff Council governed a county borough, separate from the county of Glamorgan.
